PLOW.

SPECIFICATION forming part of Letters Patent No. 472,348, dated April 5,1892. Application filed October 5,1891. Serial No. 407,778. (No model.)

T0 at whom it may concern:

Be it known that I, JAMES L HATFIELD, a citizen of the United States,residing at Irwinton, in the county of Wilkinson and State of Georgia,have invented certain new and useful Improvements in Flows; and I dodeclare the following to be a full, clear, and exact description .of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

My invention relates to plows, and has particular reference toimprovements in plowpoints, having for its object the provision of apoint which by very slight variations in construction is adapted for useupon any form of plow, whether shovel, scraper, sweep, or turning plow.With several of these forms of plows the point is interchangeablewithout change of construction.

The invention consists in the construction and combination of partshereinafter set forth, and pointed out in the claim.

The accompanying drawings illustrate the said invention in itsapplication to different forms of plows.

Figure l is a perspective view of a shovelplow with my inventionapplied, showing a portion of the stock to which the plow properisattached. Fig. 2 is a longitudinal section of Fig. 1. Fig. 3 is aperspective view of the sweep form of plow with my invention applied.Fig. 4 is a front elevation of a turning-plow, showing a portion of theshovel or mold-board broken away to show the splicepiece. Fig. 5 iscompound figure showing a transverse section and a side or edgeelevation of the splice-piece used in Fig. 4.

Similar letters of reference indicate corresponding parts in all thefigures where they occur.

A is a plow-stock, and B is a splice-piece, which I attach thereto inconnection with the body of the shovel, sweep, or mold-board, as thecase may be. This body portion is marked 0 in all the figures, and it isconstructed with a recessed lower edge having a forwardly-beveled form,as shown at c the edge extending out from the recess being outhorizontally.

This body portion receives the top of the point D, which is of reverseform to meet and form a close fit with the body, its meeting edge havingthe central projection d and the straight sides d. The meeting edge ofthe point is beveled to fit snugly upon the beveled bottom of the bodyand give a joint whose exposed edge inclines upward and presents noobstruction to the easy movement of the dirt over the plow. Thesplice-piece extends nearly or quite to the top of the body 0 and isfastened to the plow-stock therewith by the same bolt which secures theplowbody to the stock, the hole in the body and the hole in thesplice-piece registering for this purpose. The splice-piece extends downbelowthe recess in the plow-body and has the point united to it by meansof the bolt, which passes through the projection d of the point, whichfits into the recess in the plowbody. The form of splice piece shown inFigs. 1, 2, and 3 is a simple curved piece about the width of theplow-stock and is illterchangeable in any form of shovel, sweep, orscraper-plow, and the point used in these figures is alsointerchangeable in any such plow.

It will be seen that the top of the shovel or plow-body is unchangedfrom that employed in any ordinary plow, except in the matter of makingthe recess and beveled edge, which are readily forged or cast withoutincreasing the cost of the plow-body. This is made possible by theaddition of the separate splicepiece, which takes the place of andserves the same function as the complicated construction' of plow-bodywhich is usually employed with removable points. The separatesplice-piece, having no wear upon it, can be used for an indefiniteperiod of time and have any of the interchangeable forms of plowattached to it, and when one plow is worn out a new one can be suppliedwithout renewing the splice-piece.

In the tu rning-plow the splice-pieceB is made wedge shape in transversesection and has an inclined bottom running to a point on the thick sideof the splice-piece, which thick side is set in line with thecorresponding edge of the plow-stock, which permits the inclinedmold-board or shovel to be set and secured upon it without changing thefoot ot the stock, thus saving the expense of extra forms ofplow-stocks. Upon the shovel or mold-board of the turning-plow, near thepoint, the same recess and beveled meeting edge are employed as in theform shown in Figs. 1, J, and 3, and the splice-piece extends below thisbeveled edge, as in the other forms, and receives the top of the point,which is matched to the recess and bevel of the shovel or moldboard, asin the other form. The point in Fig. 4c is pointed on the side insteadof in thocenter to adapt it to the turning-plow. The splice-piece in theturning-plow may be wider than the stock, and thus afford a brace andsupport for the mold-board and shovel.

The point in any of the forms is of course the part which takes thegreater part of the wear and needs the most frequent renewal, which canbe done without renewing or, indeed, disturbing either the plow-body orthe splice-piece, and the renewal of the pointbeinga matter of triflingcost the expense of plowing is greatly reduced and a very considerablesaving effected for the agrieulturist.

Having thus described my invention, what I claim, and desire to secureby Letters Patout, is

In a plow the combination of the plowstoel; A, a separate splice-pieceB, a plowbody 0, fitting upon said splice-piece and secured therewith tothe plow-stock by a bolt passing through the body, splice-piece, andstock, said plow-body having a central recess in its lower edge and saidsplice-piece extending below said recess, and a point-piece having aprojection fitting the recess in the body and having a bolt passingthrough said projection and uniting the point to the splicepieee, as setforth.

In testimony whereof I aflix my signatnrein presence of two witnesses.

JAMES I. HATFIELD.
